Previously, ECS service discovery only supported tasks launched using the awsvpc networking mode, which assigns each running task a dedicated elastic networking interface.

Now, you can use Amazon ECS service discovery with tasks launched using bridge and host networking modes in addition to awsvpc mode. This lets you use ECS service discovery for more container workloads without requiring you to make any networking changes.

You can use Amazon ECS Service Discovery in all AWS regions where Amazon ECS and Amazon Route 53 Auto Naming are available. These include US East (N. Virginia), US East (Ohio), US West (Oregon), and EU (Ireland) regions. For more information on AWS regions and services, please visit the AWS global region table.
